"A trawl of Chinese crowdsourcing websites?where people can earn a few pennies for small jobs such as labeling images?has uncovered a multimillion-dollar industry that pays hundreds of thousands of people to distort interactions in social networks and to post spam."

"The researchers discovered that a large amount of the suspect activity in China originated from two crowdsourcing sites: Zhubajie, the largest in China, and Sandaha. There, people are openly offered the equivalent of tens of cents to do things like create accounts on particular sites, post biased answers about specific products on Q&A sites, and create and spread positive messages about products on social networks."
